Not HTC. It is now the world's fifth largest smartphone maker by shipment after Nokia, Apple, RIM and Samsung, and it can challenge Apple's market share in Europe and Asia, analysts said.

Momentum is further boosted by first quarter results, which saw its unaudited net profit nearly triple from the same period last year to Tw$14.83 billion ($510 million) while revenue surged 174 percent to Tw$104.16 billion.

This year HTC boss Wang, the 52-year-old daughter of late industrialist Wang Yung-ching, was crowned Taiwan's richest person by Forbes magazine, which estimated the combined wealth of her and husband Chen Wen-chi at $6.8 billion.

"Cher Wang is more like a spiritual leader of the company. She has a good eye for talent and she supports and trusts her professional management team," Wang said.

Analysts said HTC's close partnership with telecom operators and Google has given it an edge in the business. HTC was the first to make devices powered by Android, which is now adopted by LG, Motorola, Samsung and Sony.

"HTC is in time for the rise of smartphones and it is riding the boom of Google's Android," said Luke Lin, an analyst at Taiwan's IT journal Digitimes.

Android is the most popular operating system for mobile devices, and technology research firm Gartner expects it to have 38.5 percent of the market by the end of 2011, ahead of the 19.4 percent for iOS for Apple's iPhone.

"It is going to be even better for HTC this year although it faces growing challenges for market share," said Lin. He estimated shipments to almost double from last year to about 50 to 55 million units.

"This year will see... these same (Android) vendors broaden and deepen their portfolios to reach more customers, particularly first-time smartphone users," said Ramon Llamas, a researcher at International Data Corp.

The company has also jumped onto the tablet bandwagon with its first tablet, Flyer, due to go on sale in the second quarter, although analysts said it was too early to say how it could contribute to the bottom line.

"We view this more as a product to test the market. We tend to believe tablets may not be a near-term value driver for HTC," said a recent Morgan Stanley report. It forecast fewer than two million shipped in 2011.

Underscoring the intense rivalry between smartphone makers is an ongoing dispute between HTC and Apple, which have accused each other of patent infringement and appealed to the US International Trade Commission to bar the other's products.

"An unfavourable ruling will certainly impact its (HTC's) operations," said Lin of Digitimes.
